Restore computer problems

Recently my computer froze, i turned it off, turned it back on, and just kept loading and loading and loading. I tried the command+S thing and the terminal kept saying it couldn't find root mount, errno 19... Or something like that. I took it to geek squad and they told me to try to restore it (command+R). So i took it home and did that. I tried installing mac os lion but it didnt give me any options to put it on. NOTES: I'm able to get to disk utility.

Which version of OS X did your MBP ship with? From your question, it seems that you don't have restore disks. If it shipped with Lion, then the CMD+R thing should work. If it shipped with Snow Leopard, it is possible for this to work with a firmware update (depends on the model). Which MBP do you have?
